Sorry to hear that but you will either have to sand the spot you want the tri laser and housing on or just glue it on but run the risk of the glue not taking properly, you will have two options to run the wiring for the laser either drill a hole in the bio and run the wiring through that into the bio or make sure the tri laser housing is long enough to reach the rear of the bio and run the wires around the back of the bio. Hope thy makes sense. Mike
